GP Primer is a high-performance, water-based roof coating primer designed to improve adhesion on cement roof tiles. It prepares both smooth and rough cement tiles by creating a strong bond between the roof surface and the final coating system. This helps roof coatings apply evenly and perform as intended over time.

This acrylic primer plays a critical role in roof preparation. It improves coating adhesion while also helping create a more uniform surface. GP Primer works well on a wide range of cement roof tiles and supports long-term durability and visual consistency.

What sets GP Primer apart is its dual-action performance. It acts as an adhesion promoter and a surface filler at the same time. Its high solids content helps fill minor surface imperfections, especially on rough cement tiles. This creates a smoother base before applying roof coatings and improves the final finish.

When used with NuTech Paint roof coating systems, GP Primer helps deliver a clean, professional result. It supports strong coating adhesion and helps roof coatings stand up to Australia’s harsh environmental conditions, including sun exposure, temperature changes, and weathering.

GP Primer suits residential and commercial roof restoration projects where cement roof tiles remain in good condition. Proper priming helps reduce coating failure and improves the overall performance of the roof coating system. Technical data, application instructions, and safety information are available in the product SDS.

⚠️ Important Note:
GP Primer is not suitable for oxidised or powdery roof tiles. For these surfaces, NuTech recommends using NuPrime to achieve proper surface preparation and reliable coating adhesion.
